2 Claims.

This invention relates to a folding carton and blank therefor and hasspecial reference to a combination display container which combines botha box or outer container and cushion partition, the whole being madefrom a one piece cardboard blank. 4

One important object of the invention is to provide a carton of thisclass wherein the entire contents of the container is visible andwherein the box may be covered by a transparent cover which will protectthe contents from dust, dirt and deterioration through evaporation.

A second important object of the invention is to provide a carton ofthis character having ll cushioned portions which support and protectfragile articles from breakage, the container being especially adaptedto hold glass ornaments, chocolate covered confections, hollow chocolateand the like.

go A third important object of the invention is to make this containerfrom a single cardboard blank whereby to lessen expense of assemblingseveral blanks, the entire container being formed by folding the partsinto position and there securing them without the use of adhesives orthe like.

With the above and other objects in view the invention consists ingeneral of certain novel details of construction and combinations ofparts so hereinafter fully described, illustrated in the accompanyingdrawings, and particularly pointed 'out in the appended claims.

In the accompanying drawings, like characters of reference indicate likeparts in the several views, and:

' Figure 1 is a plan view of the blank from which this container ismade.

Figure 2 is a top plan view of the container as formed from the blankshown in Figure 1.

Figure 3 is a longitudinal section on the line 3-! of Figure 2 andshowing the molded partitions.

Figure 4 is a transverse section of the line 4-4 of Figure 2 andparticularly showing the mannerof forming the middle rib and a face ofone of the transverse partitions.

Figure 5 is a section, on an enlarged scale, on the line 5--5 of Figure3, the section being fragmentary and showing merely the lockingarrangement by which the blank is held to form the completed container.

Figure 6 is an enlarged detail bottom view of the interlocking. means ateach end of the con- 15811181.

Figure 7 is a perspective view of the complete container.

In the embodiment of the invention as herein disclosed the blankconsists of a rectangular body portion ill having relatively long sidesand rela- 5 tively short ends and to the body portion iii are connectedbottom portions II, the bottom portions being defined from the bodyportions by weakened or fold line l2 extending from end to end of thebody portions. Each of these bottom 10 portions is of generalrectangular form but the outer corners thereof are rounded as at I3. Tothe edges of the portions H which are parallel to the fold line l2 areconnected central rib portions ll which are defined from the portions ll by 16 weakened or fold lines l5.

Body portion In consists of a central part l6 and side parts I'I. Theseparts l6 and H are defined from each other by a series of spaced slitsl8 so that each series of slits forms a weakened or fold 20 lineenabling the side portions to be readily folded into position at rightangles to the central portion Hi. The slits at one side are arrangedopposite the slits on the other side of the central portion and thusform spaced pairs. The slits of 55 each pair have their ends connectedby weakened or fold lines l9 so that the parts I! are connected bytransverse top portions 20. The portions between each pair of the sideslits l8 and the pair of fold lines l9 constitute transverse partitiongo forming portions which are separated centrally between the fold linesl9 by crenelated slits 2i having opposed V-notches 22 formed in theirseparated edges at the middle portion thereof.

At each end of the body portion l0 there is 35 provided a pair of endflap members 23 which are aligned with the side parts l1 and are definedtherefrom by a fold or weakened line 24. At each end of the centralportion it of the body Ill there is provided an end wall 25 which isdefined from 40 the portion In by a fold line 26. The portion 25 isseparated from the portion 23 at each end by slits 21. Connected to thatedge of the portion 25 which is parallel to the fold line 26 is a bottomflap portion 28 which is defined from the respective portion 25 by aweakened or fold line 29. Each fold line 29 is provided at its centerwith a slit 30 extending longitudinally on the fold line and on eachporttion 28 is a slit 3| parallel to the slit 30 and connected to theslit 59 v 30 by a transverse slit 32. Thus there is formed an H-lockingslit in each end portion. Each of the portions It has at its ends aT-shaped member 33 which, as will be seen hereafter, engages in theH-shaped locking slit at the respective ends. is

- Furthermore, the outer or free edge of each portion It is providedwith a series of spaced notches aligned with the fold lines l9.

In setting up the device the blank may be laid on a flat surface andthen the parts I 1 are bent up at right angles to the part Hi to formthe lon-' gitudinal sides of the carton. After this the bottom portionsH are bent over on the fold lines I2 to lie in a plane parallel with theportion l6 and the central rib portions H are bent on the fold line l5to extend toward the portion l6 and contact with the transverse portion20. Prior to this, however, the transverse partition portions with theircrenelated edges are bent substantially at right angles to the portion20 so that the notches 22 and the notches 34 may interengage and holdthese parts in position. Next the parts 25 and 23 are bent on their foldlines so that the parts 25 lie outside of the part 23.

tion 25 and tucked in so that one side of the T- shaped portion 33 canengage in the H-slot in the middle of the end portion.

When this is done a carton is provided with side walls between which isa central wall or rib 'and said carton also is provided with yieldableor Sylphrap adhesively secured to the sides and end parts of the cartonor such carton may be entirely wrapped in material of this character.

It will now be seen that the carton is formed from a single piece ofcardboard or other like material and that there is substantially littlewaste in the cutting of the blank forming the device. It will also beseen that the device is very readily assembled and requires no adhesivefor holding the parts together and, when so assembled, forms a ruggedand substantial carton. Finally, by means of the crenelated edges andmovable transverse walls very delicate material may be supported in thecarton without danger of fracture or other injury.

Finally, the end tabs 28 are bent at right angles to the por- What isclaimed, is:

1. A carton formed from a single blank of suitable cardboard-likematerial cut and scored to form a bottom, sides and ends, the bottombeing scored to fold lengthwise to form a longitudinal partition,integral portions connecting the sides to form transverse partitionsinterlocking with the longitudinal partition to provide a series ofindividual compartments, each of said transverse partitions comprising atop member and a pair of parallel depending walls integrally connectedto the top member, said central and transverse partitions havingco-acting notches with the notches of the central partition being widerthan the thickness of the central partition thereby permitting yieldingmovement of said central partition.

2. A carton blank comprising a body portion of rectangular form having acentral part forming portion adapted to constitute transverse top andpartition. wall members, each of the parts forming the partition wallmembers consisting of a pair of wall portions divided by a crenelatedslit and having a fold line at the opposite edge from the slit, each ofsaid transverse walls forming portions having a central notch on thecrenelated side, said body portion having side forming portions definedfrom the transverse wall portion by aligned slits, bottom portionsconnected to the outer edges of said side portions and defined :t'

therefrom by fold lines, central rib forming portions connected to theouter edges of the bottom forming portions and defined therefrom by ioldline, said central rib forming portions being provided at their outeredges with pairs of spaced notches and at their ends with substantiallyT- shaped lock engaging means, end portions projecting from the ends ofsaid central portion and defined therefrom by fold lines, locking tabsprojecting from the outer edges of the end portions and definedtherefrom by fold lines, H-shaped slits formed centrally on said flaps,and fiaps extending from the side portions and defined therefrom by foldlines, and means on the end portion to engage said T-shaped lockingportions.
